Surname Igarashi. A second-year student and the brain of the Gehenna Revival Committee. Since the other members aren't particularly fond of intellectual tasks, she effectively serves as the strategist directing the committee's path. She maintains an intelligent and polite demeanor, plans meticulously, and is a skilled orator. Her weapon of choice is a Borchardt C93, the receiver of which is hidden by her skirt. She holds ideologies that directly clash with both Makoto and Hina, seeking to control and dominate the chaotic and free-spirited Gehenna. She often arbitrarily fabricates the Sensei's inner thoughts, adding comments like "This is what you were thinking." She has long black hair and is seen carrying a pink book, wearing black gloves with the Gehenna uniform, and holding a light brown bag.
